Abstract: PURPOSE:To effectively prevent a water leakage into a secondary lining by forming a specific porous water permeable layer and a specific waterproofing film layer between primary and secondary lining concrete layers. CONSTITUTION:A water permeable material capable of forming a water permeable layer 4 having compressive strength equal to or more than 1kg/cm<2> and a water permeable factor equal to or more than 5X10<-4>cm/sec. is sprayed to the surface of a tunnel wall where primary lining concrete 3 is sprayed. Then, an aqueous waterproof material capable of forming an aqueous waterproof layer 4 having bond strength equal to or more than 0.1kg/cm<2> for the water permeable layer 4 and a water permeable factor equal to or less than 1X10<-6>cm/ sec. is sprayed. Then, secondary lining concrete 5 is additionally placed. In order to form the water permeable layer 4, an inorganic composition expandable at normal temperature is, for example, used to form the prescribed foamed porous water permeable layer 4. Then, aqueous waterproof paint made of the first and second liquids is concurrently sprayed to the surface of the layer 4, thereby forming the waterproof layer 4.

Title: Gradation display method for liquid crystal display device
Inventor: OTANI TOSHIYA
IPC: G09G3/36
Filed: 1991-12-04
Abstract: PURPOSE:To improve the display quality of a liquid crystal display device by allowing the gradation to have linearity by adjusting the lighting dot distribution of each frame in a frame thinning-out system. CONSTITUTION:The device is constituted so that among 16 gradations, 4/8 in which the ratio of the number of lighting dots to the number of dots per a unit area of a liquid crystal panel is equal to 1/2 of the gradation number 6 is inserted into the gradation number 7 and luminance becomes higher than the gradation number 6 as a dot distribution so that the lighting dots become continuous hourly on a data transmitting side. In this case, the ratio of the lighting dots becomes the same as in the gradation numbers 6 and 7, but the pattern of the gradation number 7 executes an expansion of 8 frames, and continues the lighting dots. Since the pattern of the gradation number 6 is discontinuous, an applied voltage waveform to a liquid crystal rounds frequently, and the luminance of the gradation number 7 becomes higher. Also, the ratio the lighting dots is smaller than the gradation number 7 (the ratio of the turn-on dots is 4/7) of the gradation number 7 in a conventional example, therefore, the luminance of the gradation number 7 by this system is reduced.

Abstract: PURPOSE:To prevent the wrong instruction of a reproducing operation by detecting the exchange of a recording medium and transmitting a detected result to an external device. CONSTITUTION:A computer 30 outputs an 'ID transmission' instruction to a still video reproducing device 10 so as to know the recorded picture of a track where a magnetic head 12 is currently positioned. Thus, a system control circuit 26 transmits the reproducing ID data to be outputted from a demodulation circuit 22 and the status signal of the reproducing device 10 through an interface circuit 28 to the computer 30. At such a time, when a magnetic disk 11 is exchanged out of the control of the computer 30, a disk load detection circuit 24 detects the exchange of the disk and sends the detected result to the control circuit 26. At the time of a response to the 'ID transmission' instruction, the circuit 26 notifies these information to the computer 30.
